I disagree, in my experience biwiring makes a sizeable difference. My early expeience (late 1980's) with biwiring involved DIY mods to standard speakers (some very early MA with metal dome tweeters, Rogers LS6, Celestion SL600). We did mono testing first, ie moded speaker against unmoded. Using the same cable for tweeter and woofer give significant results- even blind tested with people with no interest in hifi. Using different cable for top and bottom gave better results as it was possible (by carefully choosing the appropriate cable) to tailor the sound (no tone controls required)
The question of brass jumper plates did not come into it for us.
My best advice is to try it out yourself with some cheapish cable, single against biwired. The biwire virtures I have heard are:
1. Tighter less boomy/boxy bass
2. Sweeter top very noticeable on femail voices, cymbals played by a jazz drummer and trumpets
3. When you listen in stereo, The sound stage is bigger with more depth
Though the degree of improvement varied from speaker to speaker and cable combinations, the way it improved the sound seemed constant.
If you find you don't hear a difference then go for a decent set of single cables. If you do hear a difference well... But please do test yourself because it is clear that some people can't hear a difference while others like me can.

Your experience with biwiring was so good, you haven't done it since the late 1980s.
